One of the things that's driving films in a particular direction is that the after market value of them is dropping really fast and in many segments of it, not just DVDs. Pay television is dropping.
I don't know why, it's the same reason why you like some music and you don't like others. There's something about it that you like. Ultimately I don't find it's in my best interests to try and analyze it, since it's fundamentally emotional.
